A population of bacteria is growing according to the equation P ( t ) = 1050e^0.16t .
horsena [70]

Answer:

t must be greater than 5.0

Step-by-step explanation:

P ( t ) = 1050e^0.16t

We want P(t) > 2337

2337 <  1050e^0.16t

Divide each side by 1050

2337/1050<  1050/1050 e^0.16t

Take the natural log of each side

ln (2337/1050)) < ln(e^0.16t )

ln (2337/1050) < 0.16t

Divide by .16

ln (2337/1050)/.16 < 0.16/.16t

ln (2337/1050)/.16 < t

5.00049<t

Identify the variables in this Algebraic Expression<br> X+ 4y - 9
Lesechka [4]

Answer:

The expression x + 4y - 9 has two variables x and y.

Step-by-step explanation:

<u>What is a variable?</u>

A variable is a letter, for instance x or y, that represents an unknown number.

Given the expression

x + 4y - 9

The given expression has three terms which are x, 4y, and -9.

Here:

  • The term 'x' is the unknown variable x.
  • The term '4y' has a coefficient (the number next to a variable y) of 4.
  • The term '-6' is a constant.

As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.

Thus, the expression x + 4y - 9 has two variables x and y.
